The snare assembly includes a snare, a snare operating device, and a cable. The external magnet includes a second coupling surface. The polar orientation of the external magnet is opposite the polar orientation of the internal magnet such that the first and second coupling surface are magnetically attracted. The pull wire system includes a needle, a cannula and a pull wire. The feeding tube assembly includes a tube, a snare, a connector, and a dome fixed to the tube. A method of use is disclosed.
